For how long after stopping Nystatin can lumps in the vagina be visible?

As I understand it, you mean the presence of lumps in the vaginal secretion. An element of vaginal self-cleansing is mucus, the amount of which depends, among other things, on the phase of the cycle. Nystatin in vaginal tablets is used at a dose of 1 – 2 tablets per day. Similarly, most other vaginal preparations are used once a day. Therefore, in my opinion, under standard conditions, the remnants of the vaginal tablet should not come out of the vagina for more than a day or two. However, as I mentioned, this is a process that can be individually variable and there are situations of extremely long persistence of the drug in the vagina: https://www.gdziepolek.pl/opinie-i-pytania/72140/co-mam-zrobic-jesli-mam-w-pochwie-duza-kulke-po-kuracji-albothyl https://www.gdziepolek.pl/opinie-i-pytania/15825/fluomizin-czy-lek-fluomizin-powinien-rozpuscic-sie-w-pochwie https://www.gdziepolek.pl/opinie-i-pytania/11249/czy-wyciek-skladnikow-globulki-dopochwowej-jest-normalnym-zjawiskiem
